When the temperature drops, this ultralight, stylish, insulating parka with keep you toasty to the core. A DWR treatment resists rain, sleet and snow, and allows for wear as an outer layer in unfriendly winter weather.

We don't have any way of providing temperature ratings for a jacket. It's a medium-thickness down jacket, but your results will vary widely based on wind, humidity, what you're wearing underneath and how cold-natured you typically find yourself to be... much like with sleeping bags!

It's not waterproof -- the DWR treatment will repel snow for a while, and light rain will bead up, but eventually the jacket will wet out if you're wearing it in a rain shower. OR doesn't publish a "center back length" for this, but it should fall just above the knee.
